The issue that you experience is caused by our DockingManager control. It has been obsolete for almost two years and we removed it from our suite in Q1 2011. The issues that you experience with DockingManager are addressed in the new docking control implementation - RadDock
. To use RadDock, please update your Telerik version to the latest ones.
Write back if you have additional questions.
